ELE109 Instrumentation and Data Networks

Course description for academic year 2018/2019

Contents and structure

As the title indicates, the subject holds two modules, instrumentation and data networks respectively.

Within the instrumentation module, the subjects are accuracy, noise, dynamic characteristics, and reliability in measurement systems. Furthermore, sensing elements, signal adaptation, signal processing, and data presentation are covered. Finally, specialized measurement systems, such as temperature gauges, flow meters, optical measurement systems, and intrinsically safe systems are covered.

The module "computer networks" covers fundamental principles, such as transmission medium, modulation techniques, the OSI model, network components and communication protocols. Finally, the module reviews principles of TCP/IP-based data networks and various industrial networks, such as Profibus and Modbus.


  • Measures and units
  • Position, velocity, pressure, fluid flow, level and temperature sensors
  • Choice of sensors, signal processing, transmission and signal presentation
